Save your energy

MAR-IX fresh-air units are equipped with a heat recovery system which reuses up to 60% of the energy of the extraction air. This inventive solution reduces the cooling and heating capacity so that you can fit smaller chiller units and heaters. What’s more, a smaller generator can be used to further lower costs.  A ventilation system with heat recovery function consists of two units. The supply unit (FAM) filters the incoming air through a built-in High Air Flow (HAF) air filter and F9 filter. The fresh air is then acclimatised and dehumidified before being blown into the vessel with a slight overpressure. Dirty air from the cabins, showers, toilets and other spaces is removed by an extraction unit (RAM). The fresh-air supply unit and extraction unit are connected by a liquid pipe and with liquid used for energy transport there is no mixing of air.
